What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlcoholic beverages and the main metabolite of alcohol, acetaldehyde, are known carcinogens. A genetic variant in aldehyde dehydrogenase 2 (ALDH2, G>A, rs671) leads to decreased efficiency in metabolizing acetaldehyde and is associated with an increased cancer risk. As alcohol consumption is a modifiable risk factor for various cancers, the identification of ALDH2 deficiency presents an opportunity for precision cancer prevention.
methodsOur primary objectives were to examine the prevalence of ALDH2 deficiency and alcohol consumption behavior among affected individuals within a large, diverse US national cohort. The prevalence of ALDH2 deficiency was determined by examining the rs671 genotype among 311,290 participants within the All of Us Research Program. Relationships among self-reported alcohol consumption, sociodemographic factors, and the rs671 genotype were analyzed.
resultsALDH2 deficiency was most prevalent among individuals who identified as Asian, among whom 23.5% had at least one deficient ALDH2 allele compared with <2.5% in all other racial/ethnic groups. Among those with one and two deficient ALDH2 alleles, 61.2% and 24.4% reported drinking in the past year, respectively, and of these, 30.3% and 16.0% reported binge drinking. Multivariable analysis showed that ALDH2 genotype, sex, age, race, education, income, employment, marital status, and country of birth were associated with alcohol consumption behavior.
conclusionsMost individuals with ALDH2 deficiency reported drinking alcohol in the past year, and consumption was associated with various sociodemographic variables, particularly sex, age, and country of birth. IMPACT: Our findings suggest a significant opportunity for precision cancer prevention targeting the unique prevalence of ALDH2 deficiency among Asian Americans.
